Hi!
I am new to this forum and kind of new to diagnosing electronics.. maybe I have ruined the whole board.
I guess this is basics, maybe someone could point me in the correct direction for what I could do.
The laptop is a Asus Zenbook Flip UX360UA only a year old, it has a chassis damage caused not by
falling or getting hit, but the edge of the screen hitched a table (bad table for laptops) and got bent so the store who sold it
is not accepting it on warranty. Anyways, what could get worse, was my thought..
At first when connecting 19v the power led blinked for <200ms and turned off every time.
The whole board has 19v, the power on button had 3.3v (not anymore), after diagnosing the 19v rail it seemed
that one of the power supplys didnt get 19v, and I tried to short the mosfet (marked in red), and the laptop powered on,
charging led started to blink and the screen turned on. Great success... until the laptop turned off, and the
power led faded away into oblivion..
Now there is no leds blinking, no 3.3v on power button, bios chip has 0.1v and it's dead. Hearing a click from somewhere
near the power supply connector. Now the components marked in green heats up to the point where there is not
possible to touch them, and I guess there is a short somewhere.
When measuring the caps before and after the mosfets some seems to be shorted, some not. Even caps on the power supplys
to the right of the board seems shorted.. so I guess I have to buy a capacitor tester?
Anyways, anyone with a clue of what to do next?
